Superbox boilers can also be combined in cascades of up to 16 boilers for maximum flexibility.

For even greater flexibility, the integral master control panel provides control of up to three different zones. Superbox boilers are also designed for ease of installation and maintenance.

Further flexibility is provided by a fully modulating pre-mix burner with up to 7:1 turndown capabilities.

They are available with matched mounting frames and cascade hydraulics including low loss headers or matched system separation plate heat exchangers. The range features built-in frost protection and time control, with direct BMS connectivity and remote monitoring options.

All models are suitable with natural gas or LPG.
